Intake Actuator Repair Procedures

Inspection

1. 1
   Turn the ignition switch to the OFF position.
2. 2
   Disconnect the intake actuator connector.
3. 3
   Check that the intake actuator operates to the fresh air position when 12 V is applied to terminal 3 and ground to terminal 4. Check that the intake actuator operates to the recirculation position when the polarity is reversed.

   

   1. - 2. - 3. Fresh Air 4. Sensor (+5V)

   5. Feedback Actuator 6. Sensor Ground 7. Recirculation Air

4. 4
   Connect the intake actuator connector.
5. 5
   Start.
6. 6
   Check the voltage between terminals 6 and 5. Specification

   Door Position	VOLTAGE (V)	Fault Detection
   Recirculation	– 0.3±0.15 V	Low voltage: 0.1 V or less
   Fresh Air	– 4.7±0.15 V	High voltage: 4.9 V or more

   
   There will be feedback on the current position from the actuator to the control unit.
7. 7
   If the intake actuator does not operate properly, replace it with a known good intake actuator and verify correct operation.
8. 8
   If the intake actuator is faulty, replace it.

Diagnosis with GDS

1. 1
   The heating, ventilation and air conditioning (HVAC) system can be diagnosed quickly (defective parts) using the Global Diagnostic System (GDS). ※ The GDS provides the following information. (1) Self-diagnosis: checks and displays diagnostic trouble codes (DTC). (2) Current data: checks the status of input/output signals. (3) Active test: checks system operating conditions. (4) Additional functions: in addition to control, such as zero point adjustment.
2. 2
   Select the "Vehicle Model" and the system to be checked in order to inspect the vehicle with the scan tool.
3. 3
   Select the "Current Data" menu to check the current input/output status. The input/output data for the sensors related to the intake actuator can be checked.

   

4. 4
   To perform a forced operation on the intake actuator input factors, select "ACTUAL TEST".

   

REPLACEMENT

1. 1
   Disconnect the negative (-) battery terminal.
2. 2
   Remove the assembly from the protective cover. (Refer to Body - Main Instrument Panel)
3. 3
   Disconnect the connector, then remove the intake actuator (A) after loosening the mounting screws.

   

4. 4
   To install, perform the removal procedure in reverse order.
